The DNA to dare is still alive and well!
The picture on the left is of our previous president with the Taguchi shaft tower that laid the Company’s cornerstone. The spirit of those days, to dare to take on challenges and build something from nothing, is still alive and well.As we approach 100 years since our founding, we will continue making new suggestions.
Shouldering expectations and taking pride to heart.
Our staff meet customer expectations at sites throughout Japan.The motivation is pride in supporting Japan’s infrastructure along with all of you.
*Our Production Division includes the number of employees at Hatten Kogyo Co., Ltd.
Our sales prove that we overcame challenges.
We have thought every day about solving customer issues. Our steady sales are no more than the results of that consideration. We look forward to other new challenges at the next new sites.Taguchi Industry is even now striving with the latest technology to solve those issues.
Solving site issues with patents.
Our continuous belt conveyor systems remove sediment from tunnel faces outside the shaft.In response to requests from customers to apply this technology to the removal of sediment from centrally conducted invert construction, we developed a structure to carry sediment from the middle of the conveyor.Customers were delighted to receive what they asked for, making this a profoundly memorable patent.
[Japanese patent number] 6707609
[Invention title] Facility of crushing stones and sand in tunnel construction
Market share:
Continuous belt conveyor systems
A top share continuously
protected through changeCurrent President Issei Taguchi assumed office in 1995. Seeking new technology to support Taguchi Industry in the future since then, he discovered the continuous belt conveyor system implemented in Germany at the time.Before long, the engineering staff were dispatched to Germany. Taguchi Industry acquired that expertise, and in 1997, we delivered a blasting-debris continuous belt conveyor system to Kyushu Shinkansen Tagami Tunnel. It was the first introduction in Japan of this revolutionary construction method.Since then, we have accumulated improvements including curve handling and compacting, and we have proudly held the top share from initial development to the present day. Our delivery record surpassed 200 sites in April 2022, and our current domestic share is 90%. Going forward, we will continue to refine technology in order to support tunnel construction in Japan from behind the scenes.
Taguchi Industry endorses the Sustainable Development Goals advocated by the United Nations.
We have begun with what we ourselves can do.
We will continue to take on new challenges, beginning with the initiatives below.
64%reduction in CO2 emissions
Reduction through continuous belt conveyor systems
Comparing the amount of carbon dioxide generated by the method of removing sediment from tunnel excavation from the shaft using a dump truck and by removing it using our continuous belt conveyor system, our system emits 266 t of CO2 versus the 706 t of CO2 emitted using a dump truck (according to an in-house study). We cut roughly 64% of the carbon dioxide arising from sediment removal in tunnel construction. In addition, no dump trucks need to drive in small yards, contributing greatly to safety measures in the work environment.
87%reduction in deforestation area
Reduction through inclined equipment
Transporting construction materials and heavy equipment to worksites in high locations requires roads for taking a long approach by vehicle. For example, a site with a 45 m difference in elevation and a standard 12% (7.2-degree) incline means a planar travel distance of around 356 m.That increases the deforestation area.However, the planar travel distance for our inclined equipment is 45 m with a standard 45-degree incline. This allows around 87% of the forest needing to be cut to be left as is, compared with building roads.
